A walkathon (walk-a-thon), walking marathon or sponsored walk is a type of community or school fundraiser in which participants raise money by collecting donations or pledges for walking a predetermined distance or course. They are similar in format to other physical activity based fundraising events such as marathons and cycling races.
The first known walkathon was held in San Juan, Puerto Rico in 1953 by the most famous and influential actor/comedian in the history of Puerto Rico, Ramón Rivero, better known as Diplo. He walked 80 miles (from the capital city of San Juan to Ponce, on the other side of the island, to raise money for the Liga Puertorriqueña Contra el Cáncer (the Puerto Rican League Against Cancer). In that wakathon, Ramón Rivero raised the equivalent of $85,000 in 4 days. The walkathon turned into a historical event that became part of the collective consciousness of Puerto Ricans all over the world, and has been copied several times since.
